Abstract: A Generic Access Network Controller (GANC) for providing both location and charging information from a Generic Access Network (GAN) to a core network. During registration of a mobile station (MS) the GANC determines a Charging Cell Global Identity (Charging-CGI) and a Location Cell Global Identity, (Location-CGI) for the MS and stores the CGIs in an MS context. The MS sends to the GANC, a request to establish a signaling connection, and includes an Establishment Cause IE indicating a reason for the connection. The GANC selects from the MS context, either the Charging-CGI or the Location-CGI based upon the Establishment Cause IE, and sends the selected CGI to the core network in a message triggering a signaling connection.

Abstract: A system and method for adapting circuit-switched payload transport between a mobile station, MS, (30) and an unlicensed-radio access network utilizing the Real-Time Transport Protocol, RTP. The MS (30) and an access network controller (103) negotiate the number of speech/data frames per RTP packet during the assignment of a traffic channel. The network controller notifies (62) the MS of a requested or minimum acceptable sample size, and the MS utilizes that sample size, if able, to send (86) RTP packets to the network controller. If the MS is not capable of utilizing that sample size, the MS utilizes the closest sample size that the MS can support to send (89) packets to the network controller. The network controller then calculates (90) the sample size utilized by the MS and utilizes (91) the calculated sample size in transmissions to the MS. Thereafter, if network conditions change, another negotiation is initiated (94-97) to adapt the sample size to the changed conditions.

Abstract: A method of adapting payload transport between a mobile station (MS) and an unlicensed-radio access network controller (UNC) using the Real-Time Transport Protocol (RTP). During the activation of a traffic channel, the UNC and MS negotiate an initial sample size for the payload to be carried in each RTP packet. Thereafter, if network conditions change to the point that a different sample size is needed, another negotiation is initiated to change the sample size for the ongoing session. The UNC may suggest a sample size, and the MS selects the closest sample size that the MS can support and uses the selected sample size in RTP packets that it sends to the UNC. The UNC checks the received RTP packets and automatically adopts the sample size utilized by the MS. The UNC and MS may also negotiate changes to redundancy coding and other parameters that affect voice quality.
